Question

ou The area a circle is 36mp q ert
find its circumference​

Answer 1

Answer:

area of circle(Ac) = π * r^2 --------------eq1

circumference of circle (Cc) = 2*π*r ----------eq2

where r is the radius of circle

from eq 1

π * r^2 = 36

=> r = 6/√π

from eq 2

Cc = 2*π*r= 2* π * 6/√π

circumference = 12 √π = 21.27 m
